A traveling salesman is in a small town in the midwest, when his trip is suddenly prolonged for an extra month. He was already getting bored there and over the course of the extra month he becomes very homesick.

Finally, he decides to give in to temptation and visit the local brothel. He walks up to the madam and hands her a hundred dollars and says, "Give me the worst blowjob in town."

The madam says, "For this kind of money, you can have the best blowjob."
